,l TPHES FIRE-HOSE BRIDGE.

Application filed .Tune 28,

To @ZZ whom it may concern v Be 1t known that I, JAMES. SAMinr. limosvTON, a citizen of Canada, and a resident ot 0ttawa, in the Province of Ontario, Dominion of Canada, have invented a new and Improved Fire-Hose Bridge (for. which I have iiled an application in Canada February 13th, 1922, Patent No. 263,583), of which the following is a full, clear, and eX- act description.

It is one of the objects of this invention to provide means whereby at the time of a fire in a building situated on the line of a street railway or other vehicular traiiic that a fire hose can be attached to a fire hydrant, fire plug or fire engine, situated on the opposite side of the street or road to that on which the building is on fire, in such a manner that the railway or other vehicular tratcl will not be stopped owing vto iire hose laying across the surface of said railway or road.

It is a further object of this invention to construct a device of this character in such a member that it may be quickly put into action by men of a fire brigade and as quickly removed.

With this and other objects in view, the invention consists essentially in the novel construction and arrangement of parts hereinafter more fully described and illustrated by the accompanying specification and draw- 1n s.

1 eferring to the drawings, in which like characters of reference indicate corresponding parts in each figure.

' igure l is a side elevation of the device in upright position.

igure 2 is a similar` view of the device in lowered position. Y

Figure 3 is a detail view of the hinge joint.

In the drawings .Y represents 'the trolley wires, my device consisting of a metal standard E designed to support and carry a tubular section P adapted to form the cross arm of the hose bridge and provided at each rend with male and female hose threads M.

The section P is made preferably of brass, copper or steel piping and may be provided with a covering of rubber or other suitable material to insulate it from the trolley wires. I is a supporting member for the section P fixedly secured thereto at the top end by means of a plate bolted on the member P substantially midway of its length and 1922. serial No. 571,397.

fixedly secured to the member I. N are sockets formed on the member I adapted to support the braces J provided with clamps to embrace the section P and ,fully secured thereon by bolts R.

F romthe foregoing it will be seen that the hose section P and short supporting member I form one complete section which is designed to iit into a socket F in the top of the standard E to be securely held there by means of a set screw lever G.

Having dealt with the upper end of the standard E, the lower end or base is provided with a hinge or movable joint U for the purpose oi' attaching or detaching it. This joint is formed with a notch or pocket X in the moving and stationary parts and is designed to engage with the pivotally mounted dog V on the standard E, the dog bein'g provided with an operating handle W'. Y This section is composed of a brass, cop per, iron or steel pipe of a suitable internal diameter, and in cases where the same is used where overhead electric trolley wires are in use, is covered or insulated with rubber or other suitable material as a precaution against contact with electric wires through careless handling.

On each end of hose bridge P. P. is fixed a male or female hose thread denoted by M. M. preferably on an obtuse angle.

This hose section is secured permanently and centrally to a section denoted by I. of

standard E. by a clamp in two halves and bolted thereto, and is denoted by letter I?.r

The weight of hose bridge or section P. P.

is supported by wrought iron braces J. J'. secured into sockets N. N. on section I. and bolted onto collars O. O. at the required distance on P. P. permanently. Thereby making the hose bridge and short section I. one complete section of my said ire hose bridge.

The end of section I. is inserted into socket F. on standard E. and is held fast therein by set screw lever G. Eye ring on collar'H. on standard E. is for the purpose of attaching a rope used to pull fire bridge standard into a vertical position, also for lowering same. l

In connection with this improved re hose bridge a cast iron boX, or socket, (of square shape, having a heavy iron cover lined with a rubber ring for the purpose of keeping out water, is sunk permanently on the center of a street, or road, denoted by llO it. opposite to a fire hydrant, lire plug, or tire engine, and is denoted by B. The depth of this socket, or metal box, to be to suit the material of which the surface ot road, or street, is made.

The short standard or section denoted by C. is of suitable height above ground line and made of approved metal, one end" of which is square to fit into the metal box, or socket, denoted by B. The top end of section C. is round or cylindrical.

The device is operated" in the following manner. Section C. is placed in socket B, the tail end ot standard' E. is placed inside the top ot section C. The collar a short distance from end of standard E. resting on collar or flange on the topl of section C. Set screw lever l). is then made tight. The weight et standard Ff. being borne by portlable standard Q.

Fire hose bridge section l). P. is then placed in avertical position but leaning slightly towards standard E. and is connected to standard F. by the short section I. andl secured in socket F. by set screw lever G A rope is secured to eye-ring denoted by H. on standard Enfer the purpose of pully ing standard E. into a perpendicular position assisted by firemen raising standard E. and water bridge l?. P. Y

The clutch or locking bar denoted by V. will then fall into slots or pockets X. cut on hinge U. and' be securedl therein byset screw lever W. when standard E. is in a perpendicular position.

The fire hose section l). P.' now being parallel with the line of road or street, or with they railway rails, set screw lever V. on section C. is loosened.

Iron or hardwood levers denoted by S. S. are inserted into sockets T. T. on the section C. and standard E. is turned onthe previously described flanges by the firemen, so that the lire hose section l). l?. will .lay transversely to the car rails, street or line oit' traffic, and above the line of; street car trolley wires, thereby allowing a line of up andi down vehicular trailic tofpass under same.` Set screw lever V. is then made tight.V Fire hose is then connected tothe male or female threads on end ot section l). l). by drawing a brigade latter truck under saine. y

The wrought iron portable standto be used only during erection or removal..

ln cases where fire hydrant, lire plug or engine hasmore than one outlet for lire hose, two or more of the cast iron boxes are to be sunk in road bed in liront of each other or at any suitable distance from each other for the erection of more than one re hose bridge.

Furthermore, by the construction shown and described, the entire device may be erected or dismantled in three sections and any one section easily handledby the men of a lire brigade, and transported to and 'from a tire on a brigade latter truck;

llavingnow particularly y described and ascertained the nature' of my said invention, and in what manner the same is to beperformed what l do claim as invention `and desire to secure by Letters Patent is- 1. A tirel hose bridge comprisingin combination with socket means in; the ground a pedestal formed with a socket, al removable standard adapted to t intothe pedestal and provided with a hinge joint, top supporting member designed to'iit into'ith'estandard and a tubular cross member formed with hose threadedfends securedV to said supporting member, means for lockin'gthe supporting membersv and the standard and means for locking the hinge joint and means for turning the standard memberaround.

2. The combination with' ahre` hose bridge, of al socket or box ot suitable metal built into a street or road, a suitable standard, a detachable section of fire hose supported centrally on top lot' said standard, and suitable means tor locking or securing the several'sections oiI said lire hose bridge.

3. A device ot the character described in combination with a2 ground socket, a v

standard having a hinge joint and adapted at one end to lit into a supporting member adapted at the other end to receivel a support, a hose section, means orl'ocking the standard member and the section members and means for turning thestandard menibers. Ottawa, Canada, June 24th 19221.
